bnxt_en: Remove the setting of dev_port.

commit 1d86859fdf31a0d50cc82b5d0d6bfb5fe98f6c00 upstream.

The dev_port is meant to distinguish the network ports belonging to
the same PCI function.  Our devices only have one network port
associated with each PCI function and so we should not set it for
correctness.
